Soybean School: Maximizing yield with planting date and variety maturity

[ad_1]

The PRIDE Seeds Schooling Centre is into its second yr, and Matt Chapple, agronomist with PRIDE Seeds says it’s like his sandbox — the place the corporate can do research and demonstrations, have a look at completely different genetics, or trial completely different practices that may enhance yields.

On this Soybean College episode, Bernard Tobin joins Chapple in his “sandbox” to take a better have a look at maximizing yield potential by variety alternative and planting date.

Soybeans had been planted at an ultra-early, a mean, and a late planting date to find out how rising size would have an effect on yield potential, and how completely different maturity scores would reply.

Chapple notes the ultra-early seeded, 2.8 maturity soybeans (April 7) sat below some snow earlier than they emerged, and might need had frost scares early of their development, however he sees a variety of branching and pod-set proper on the backside of the stem, on the first node.

“On average, this bean has 68 pods per plant, so tight inter-nodes, it looks like we’ve kind of mitigated a lot of stress through the season, and down low, I think we can see nice pod set of often three seeds per pod,” says Chapple.

See the complete video for extra of Chapple’s insights, story continues under video:

For the common planting date (Could 19), there’s a noticeable distinction in plant top however as Chapple feedback “we made some straw, is what I’ll say.” Pod-set occurs three to 4 nodes up the plant, on this case, and the taller, extra showy plant will common 55 pods per plant, he says.

Chapple figures that the late-planted soybean (June 9) had been planted into dry situations, like a lot of southern Ontario, and that the soybean would’ve been compelled into flowering, earlier than they gained a variety of top.

“As we get into the third, fourth node, we have pod-set, but we have a higher percentage of these aborted [pods] and we have a lot slower development, more flat pods, and more one to two bean pods at these lower nodes,” says Chapple.

There are a variety of similarities within the results of planting date on the two.0 maturity soybeans — increased pod counts, low pod-set on the plant, however perhaps giving up on the chance for later flowers within the soybeans that had been planted on the ultra-early planting date.

Chapple’s take-home message? “When we look at that 2.8 versus 2.0 maturity bean, think about optimizing and really pushing your maturity group soybeans to their maximum pod count, maximum seeds per plant, when planting early and when planting in that mid planting date. When we get into that June time-frame, later in the growing season, it really warrants a dropping in maturity.”
